This invention relates to ventilators, and more particularly to an attachment ventilator which may be applied to automobiles or other vehicles. 7

One of theobjects of the invention is to provide a ventilator of compact and staunch construction which may readily and accurately be applied to automobiles and other vehicles. Another object is to provide a ventilator in the form of an attachment fitting which may be secured in place on a vehicle and adjusted to the proper position within a brief time and with littleeffort. A furthcr object is to provide a ventilator of simple and sturdy construction which may be employed in open and closed positions without causing rattling or other noise. Other objects and advantages will appear as the specification proceeds.

The invention is fully described in the following specification and shown in the accompanying drawing, in which- Figure 1 is a perspective view of an automobile equipped with a ventilator embodying my invention;

Fig. 2 is a broken plan view of a portion of the automobile, showing the arrangement of the ventilators on opposite sides of the car;

Fig. 3 is a sectional view, the section being taken as indicated at line 3 of Fig. 1;

Fig. i is an inner face view of the ventilator, the door or cover of the ventilator being in closed position; and

Fig. 5 is a sectional view, the section being taken as indicated at line 5 of Fig. 3.

In the illustration given, A represents a flange or plate which is provided with a threat B formed integrally therewith and adapted to extend through the body and innor lining of an automobile. The plate A is hingedly connected to a cover or door C. Secured within the throat B are means adapted to open and close the door G.

The plate A may be formed in any suitable shape. It is provided with a series of elongated openings 1 through which bolts may be passed to secure the plate to the body of an automobile. At its rear side, the plate A is provided with a stepped-forward portion 2 which is coiled at its end 8 to formthe inner member of the hinge. The corresponding rear edge portion of the cover 0 is similarly curved at 4 to form the outer member of the hinge. To prevent endwise movement of the telescoping hinge members, a slot 5'is formed in the hinge portion 3 and a portion of the outer hinge member 4 is turned down at 6 within the slot 5. The segment 6, together with the arrangement of the hinge members, serves as a stop to prevent backward movement of the door C beyond the position-in which it stands at right angles to the body of the car.

The door C is preferably formed with'an inwardly turned marginal flange 7 which is adapted to extend'around the plate A and to rest directly against the body of the car. Near its central portion, the cover is pro-v vided with an opening through which is passed a rivet member 8 which is provided on its inner side with an opening 9, adapted to receive the end of a spring. The edges of the cover about the central opening grip the rivet member 8 which has been forcedtherethrough, and hold it rigidly in position. The outer surface of the cover member A may be plated with any suitable material, such as, for example, chromium.

The plate member A is preferably curved at the point Where it joins the throat B and forms a somewhat flared or funnel-shaped mouth or opening 10. At its inner side, the throat B is provided with a plurality of cars 11 which are adapted to be turned over to engage the inner lining 12 of the car. With the flanged portion of plate A resting against the body wall 13 of the car, the air tunnei formed by the throat B and plate A is firmly held in position.

Mechanism for openingand closing the door C and maintaining it at such positions may be of any suitable form. I prefer to employ the following parts. In the illustration given, a cross-plate 14 is provided with reduced extensions 15 which extend through and engage slots 16 in the throat. Preferably the cross-plate is secured at one side of the center of the throat. A lever arm 17 is pivotally secured to the cross-plate 14 at an intermediate point between the censturdy.

ter of the cross-plate and one ench At iJS may be given a further adjustment to acouter end, the lever is provided preferably with a tapered edge 18 which is adapted to bear against the inner surface of the cover. At its inner end, the lever 17 is turned or twisted, as illustrated at Figs. 3 and l, to form a thumb piece 19 which lies ina plane at substantially right angles to the plane the lever. The thumb piece 19 is adapted to strike the cross-plate 14 and thus to serve as a stop against downward movement of the outer end of the lever. The thumb piece 19 is perforated at 20 to receive one end of a spring 21. The other end the spring 21 engages the perforation 9 in the rivet memher 0. With the arrangement shown, the spring 21, during the opening and closing of the door C, swings from one side of the pivot to the other. Thus it serves to hold the lever member in closed position and likewise serves to holdthe lever in openposition.

The cross-plate 18, in addition to acting as a support for the lever 17, serves to brace the throat and to permit the use of relatively thin material in forming the member. With theplate member A braced by contact with the body wall 13 and the inner end of the throat braced by contact with theinner lining wall 12 and with the intermediate portion strengthened by the cross-plate or rib 14, the air-tunnel even though formed of relatively thin material is serviceable v and In order to secure the inner lining 12 even ly about the inner edge of throat B, a ring member 22 may be employed.

In securing the attachment ventilator in position, a circular opening is first cut through the body wall and inner lining of the car at the desired point, an operation which may be accomplished very easily and accurately with tools now available. The throat B, with the ears 11 extended, is then passed through the opening until the flange of plate A rests against the face of the body wall 13. A ring 22 is then placed about the ears 11 and pressed against the inner lining 12. The ears 11 may then be pressed back against the ring 22, clamping the ring between them and the inner lining. It is preferred to have the ear members 11 suificiently long to permit the attachment to be ad justed to cars having body walls and linings of various thicknesses.

The plate member may then be rotated to the proper position, the throat member turning freely within the circular opening in the body wall and inner lining. I-Toles are then drilled through the body wall 13 in alignment with the openings 1. Screws 23 are then passed through the opening 1 and body wall 13, the screws cutting their own'threads in the body wall as they are passed therethrough. Before the screw heads are tightened against the plate member A, the plate curate positioning of the ventilator, the elongated openings 1 permitting further rotation of the ventilating device.

The door C may be opened or closed by swinging the thumb piece 19 from oneside to the other. only moving parts of the device, the lever 17 and the door C, at all times, with the consequent elimination of rattling. The telescoping hinges 3 and 4 provide a long engaging surface and hold the parts in true alignment. In the operation of the door C, it will be observedthat the stepped-forward portion 2 of the plate member A enables the door to be supported at a spaced distance'from the plate member A and the marginal flange 7 of the door engages the body wall '13 of the car at a point adjacent the outer edge of plate A. The door C serves not only to enclose the plate member A but also to house the heads ofscrews 23. p p

In order to secure a circulation of cool air through the drivers compartment, I prefer to arrange the ventilators as shown in Fig. 2. Assuming that the exhaust is on the righthand side of the car, the ventilator is turned so that the door 0 opens rearwardly. 'On the righthand side of the car, the ventilator is turned so'that the door face is in a forward direction to receive the cool air. Cool air passes through the air tunnelof the ventilator on the lefthand side of the carand circulates through the compartment and outof the ventilator on the righthand side of the car. The door of the ventilator on the righthand side of the car produces a suction which aids in inducing the uni-directionalcurrent through the drivers compartment.

In forming the plate A and throat B as a unitary structure, I prefer to use the following method. The plate A is drawn to form a cup, the sides of the cup correspond ing to the walls of throat B. I then employ a punch and die to cut out the bottom of the cup so as to leave the ear segments 11 together with a marginal edge portion of the bottom wall. A straight punch is then employed to straighten the ears 11 and marginal edge portion, the latter forming a slight ex- 3 tension of the throat wall. The air tunnel member is now ready to beintroduced into a circular opening cut through the body and lining of a car.

'The foregoing i detailed description has Tension is exerted upon the.
